INERTIAL MEASUREMENT UNIT EVALUATING METHOD AND SYSTEM THEREOF

An inertial measurement unit evaluating method is for evaluating an accuracy of an inertial measurement unit included in an autonomous driving vehicle. The inertial measurement unit evaluating method includes an image capturing step, a vanishing line calculating step, an image parameter determining step, a unit parameter obtaining step and a parameter comparing step. The left image includes a first left lane line, a first right lane line and a first vanishing point, and the right image includes a second left lane line, a second right lane line and a second vanishing point. The vanishing line calculating step includes calculating to generate a vanishing line equation of a vanishing line, which is a line connecting the first vanishing point and the second vanishing point. The parameter comparing step includes comparing the image parameter set and the unit parameter set to generate a comparison result.
